The feature to auto-block "commonly blocked numbers" is something most Android phones don't have built in. It's basically a spam filter for phone calls. (Although there are other apps that do this.) I had to change my phone number a couple years back because I was getting several robocalls per day from credit card scammers, and a normal blacklist was useless because they changed their numbers so often.
